I play game using aero cooler with jack. The problem is , when my friend cant hear me clearly but i clearly hear them out. But when i connect my 3.5 jack at the bottom, it works perfectly. Already sent to service centre once and problem solve with my phone format to factory and the technician said got problem with software. They uninstall and install the software. And now it happen again. Not my headphone/earphone problem because i've try with other phone, it works perfect.
